Due to the complexity of hand surgery and the frequent appearance of anatomical variations in this area, we show it in images and describe different anatomical variations of the wrist and hand in dissections which were realized and photographed during the last 10 years in the dissection room of the Human Anatomy and Embryology Department (Faculty of Medicine, University of Barcelona) in 100 specimens. The variations have been classified according to its anatomical components: arteries, nerves, tendons and muscles. A brief description of the variation has been realized. The aim is to call the attention on the possibility of the existence of anatomical variations, to avoid possible injuries during the approaches of the wrist and the hand.
